HAND FIRE-EXTING'UISHER- No. 830,380. i

Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed May 25, 1904- Serial No. 209,750.

To all whom it may concern.-

Be it known that I, SAMUEL MAsrIN STE- VENs, a citizen of the United States of America, residing at Manchester, in the county of Lancaster, England, have invented Improvements in Hand Fire-Extinguishers, of which the following is a specification.

This invention has reference to improvements in hand fire-extinguishers, objects being to strengthen the discharge-nozzle and improve its spraying effect on the liquid be ing discharged to enable the sealing-cap to be readily secured to the nozzle around the discharge-opening and to provide means whereby it can be readily wrenehed off and quickly removed when the extinguisher is held in the hand in the proper position for throwing and spraying the liquid and to facilitate the closing of the filling-opening.

Figure 1 of the accompanying illustrative drawings shows in side elevation the upper portion of a fire-extinguisher constructed according to this invention with the device for facilitating the removal of the cap. Fig. 2 is a plan thereof without the said device.

I Fig. 3 is a central vertical section, and Fig. 4

is a perspective view of the eap-removing device removed from the extinguisher.

The tubular body or container is provided with a tapering nozzle a, that is formed with a series of longitudinal hollow ribs or corrugations b, terminating close to the dischargeopening. 0, which is preferably somewhat larger than usual and is disposed eccentrically of the body of the extinguisher. These ribs are spaced from each other and form liquid-conduits extending approximately from the body of the retainer to the dischargeopening to convey the liquid toward. the toothed edge, hereinafter described, surrounding said discharge-opening. Each conduit is approximately of uniform depth and width throughout its length to permit a practically undisturbed flow of the liquid, whereby by means of the jets from the various conduits impinging on each other an effective spraying action is attained. Upon the nozzle a is soldered or secured a ring d, which may rest on the ends of the ribs or corrugations, although in the example illustrated it is shown slightly above them. The hollow ribs or corrugations I) serve as conduits for the fire-extinguishing liquid during its discharge by the jerking forward of the extin guisher toward the burning material and not only improve the spraying effect of the nozzle,

but also strengthen it, so that while discharge is taking place it can be pushed among goods that are on fire without risk of it becoming damaged. Teeth or projections e on the end of the nozzle project through the ring d. Instead of being turned inwardly, as heretofore, they are set so as to incline outwardly and have the effect of breaking up the stream of liquid issuing from the opening 0 and causing a wider distribution of the spray than usual. The capf is shown formed with an outwardly-extending flange that constitutes the ring d.

A hanger g, whereby the extinguisher can be suspended from any suitable support, is secured to the nozzle (1 independently of the cap f, so that the latter can be secured in place with solder that is easily broken and without wires or the like which connect the hanger to the tube-like container h of the extinguisher and necessitate the turning over of the extinguisher to enable its cap to be removed. To facilitate the closing of the filling-opening in the end of the cap f, it is formed with an annular recess i, the edge of the closing disk or plate 7' resting in said recess and its outer face being preferably flush with the surface of the cap.

To enable the cap to be easily wrenched off from the nozzle and readily removed, the extinguisher is provided with a lever m, arranged to normally extend in juxtaposition to a wall of the nozzle and adapted to engage the cap f and ring (Z in such way that when the lever is pulled away from the wall of the nozzle the cap and ring will be wrenched off. This lever m is provided with a pivoted handle or extension 72, adapted to be turned out of the wayinto a position in which it islocated over the lever m, its outer end then resting on a shoulder 0 of the lever. (See Fig. 1.)

One end of the lever m is formed as a ring 1),

that fits over the cap f, and With a tooth (1, that engages the ring (1, which is recessed at r, so that when the tooth g is in line with the recess 1" the ring p can be seated on the ring (1, when the lever can be turned partly around the cap, so as to cause the tooth g to engage with the ring (Z, the body portion of the lever being brought to the front of the extinguisher. A grooved lug or projection 8 may be provided at the front of the nozzle a, as shown by dotted lines in Fig. 1, into which the lever m may be sprung, so as to eause'it to be retained in this position. The arrangement is such that When the lever is forcibly raised; which can easily be effected by grasping the pivoted extension n thereof, the ring d and cap f are wrenched off the nozzle.

What I claim is 1. A hand fire-extinguisher comprising a tube-like. container having a tapered end nozzle terminating in the discharge-mouth, and detachable closing means for said mouth, said nozzle formed with a series of spaced internally-hollow ribs arranged approximately throughout the length thereof and converging toward said mouth and forming liquidconduits, each of approximately uniform depth throughout, whereby the liquid is jetted from the outer ends of the conduits, substantially as described.

2. A hand fire-extinguisher comprising a tube-like container having a tapered discharge-nozzle with a toothed edge surrounding its discharge-opening, said nozzle formed with longitudinal hollow ribs which terminate close to said discharge-opening and form liquid-conduits extending approximately from the body of the container to convey the liquid tosaid toothed edge.-

3. A fire-extinguisher having a nozzle with an unobstructed discharge-opening, a series of longitudinally-extending teeth or projections arranged around said opening and defiected outwardly or radially therefrom, and a detachable closing-cap on'the end of said nozzle, substantially as described.

4. A hand fire-extinguisher having a nozzle terminating in a discharge-opening, a closing-cap for said opening and a lever adapted to engage said cap and arranged to normally extend in juxtaposition to a wall of said nozzle and whereby when the lever is moved away from said wall the cap is removed from the nozzle.
